How to Perfect Frankenstein Cake
To ensure your Frankenstein cake turns out perfectly, keep these tips in mind.
-
Use Room Temperature Ingredients: Ingredients like butter, eggs, and buttermilk mix better when they are at room temperature, leading to a fluffier cake.
-
Don’t Overmix: Mix the batter just until combined. Overmixing can lead to a dense texture, which we want to avoid.
-
Level Your Cake Layers: After baking, use a serrated knife to level each layer before stacking. This ensures that your cake stands tall and looks impressive.
-
Chill the Cake Before Frosting: Allow the cake layers to cool completely in the refrigerator for about 30 minutes before frosting. This helps prevent the frosting from melting.
-
Experiment with Colors: Feel free to add more food coloring or mix colors for unique designs on your frosting or decorations.
